8 of automobiles makin Patented June 7, 1 932 v PATENT" OFFIGE JOHN A. noucx, an... or. ammonia, wesnrimrron Auromonm-easonnm mm: BAIILE Application and June 1, 1931. Serial no. 541391..

My invention relates to improvements in automobile gasoline tank baffles, and has for 'an object to provide a bafile for fastening within the inlet opening tothe gasoline tan inserting hose into the tank through sai syphon off the contents thereof while allowing the ready flow of gasoline through said opening into the tank and inserting the usual v 1 stick therein to measure the contents thereof.

Another object of my im rovement is to provide said bafile suitable or attaching togasoline tanks as an accessory automobile thereof.

Other objects of my improvementwill appear as the description proceeds.

I attain these and other objects of my'lmprovement with the device illustrated in the accompanying sheet of drawing, forming a part of this specification, in which Figure 1 is a plan view of an automobile gasoline tank showing the corner thereof containing the gasoline inlet opening thereinto, the remainder of the tank being broken away for lack of s ace and one half of the inlet cap bein bro en away, Fig. 2 is a side elevation of ig. 1 in section on a medial vertical plane, Fig. 3 is a plan view of another automobile gasoline tank showing the corner thereof containing the gasoline inlet opening thereinto, the remainder of the tank being broken away for lack of space and the cap covering said inlet opening being omitted, Fig. 4 is a side elevation of Fig. 3 partl in sectionon a medial vertical plane, and ig. 5 is a bottom lan view of Fig. 2, serving also as a bottom plan view ofFig. 4.

Similar characters refer to similar parts throughout. Certain parts are broken away to show other parts hidden thereby.

With more particular reference to the designated parts: Gasoline tank 6 has inletopening casing 9 fastened in the top thereof providing inlet opening 7 with outside end 8 of said casing. Interior screw threads 10 are provided near the upper end of the casing at a part of reduced diameter thereof. Bafile 11, preferably, in general, cylindrical in shape has side and bottom walls and an open top, with an exterior thread 12 thereon for enopening difficult to gagement wan said. thread 10 with which, preferably t makes aclose fit. The upper end 13 of t e bafile, preferably,isofenlarged diameter and is provided with interior annular groove, 14 to engage. sprin 7 clip 18 which is extended thereintothroug notches 15,15 in the top edge of end 13 of the bafile. Cap 16 fits over outside casing end 8, is fastened to spring clip 18 which, when engaged in groove 14, firmly holds the cap in place over the upper-end 13 of the bailie with gasket 17 intervening.

Diametrical slot 19 ismade across the.bot-

' tom wall of the bafileand is continued up a it may be taken off. For filling the tank the usual gasoline hose nozzle is extended into the top open end 13 of the baflle andgasoline therefrom may enter the tank through slot openings 19, 20. and 21, 21, etc. Gasoline pouring through openings 21 will strike casing 9 and is aided in freely moving downward into the tank by the illustrated oblique dis osition of said openings.

lot 19 provides forextending the usual measuring stick therethroughinto the tank. A hose suitable for withdrawing gasoline from the tank by siphoning the same off is too large for extending through any of the disclosed openings in the baffle walls and, therefore, could not be passed into the tank to contact with the gasoline therein. Therefore, my bafile discourages attempts to steal gasoline from a tank equipped therewith and provides real protection against said theft.

Figs. 3 and 4 show a simple means of fastening my baffle in tank 16 having filling opening a7 and easing a8, a9. fastened therein. A bailie similar to that illustrated in Figs. 1, 2 and 3 may be used but thread 12 its top end flush with the top end of cas- 2 i eeann;

ing a8. Ring 22 is disposed around casing a8 and has at least three openings radially therethrough and openings in km therewith are made in casing a8 and the top end 13 of the bafile, the openings in the latter bein tapped. gS'crews 23, 23, 23 are extended t iroughsaid openings in the ringand casing and engaged in the tapped openings in the baflie. Preferably, the inner ends of the screws where protruding are upset to' make withdrawal thereof diflicult.

The disclosed way of fastening rin 22, casing a8 and the top end 13 of the be. e together to retain said bafile in place serves the purpose very well and provides a cone venient method of attachin my protecting bafile to the tanks of a num er of makes of cars without removing any of the usual fixj tures thereto. The apparently irregular spacing of screws 23 is often made necessary by the presence of other features adjacent the tank inlet.

Cap a16 is made large to also cover ring 22 and is retained by spring clip 18 engaging in groove 14' as in Fig. 2 having gasket a17 between the cap and the top edge of the bafile.

Although but two particular ways of fastening my baffle within a tank inlet opening are shown above it is apparent that it is well suited for installing in man of the usual shapes of tank inlets by slig t variations thereof which have no the central idea of this invention. Also,w en

installed at the time of making the tank, the

particular sha e suitable for fastening the same in the tan is much simplified. Having thus disclosed my invention, what I claim as new therein and desire to secure by- Letters Patent is r I In a tank inlet baflie, an open-top hollow body having perforated side and bottom walls disposable within the inlet casing of an automobile gasoline tank, a ring having radial openings therethrough disposed around the outer ends of said inlet casin and baflle with said radial holes aligned wit holes through said casing and ta ped holes throu h said bafile, screws exten ed through said oles] in said ring and casing and engaged in said tapped baffle holes, and a cap fitting over said open top of the baflle engaged therewith.
